Tumbleweed Cellar
Five stops tuned to sit together without fighting — #004c71 ink anchors the set, #7ebbe5 opens it up, and #2875a2, #4690bf, #629fc7 cross the middle in a tetradic arrangement. Tumbleweed Cellar suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
